reading the way I wanted it.
Ha, ha!
The
squib batteries--our electrical briefing I
thought, · wa.s very good. Everything behaved just
the way they told me .
The squib batteries star ted
out pretty high, around 27 or 28 volts , and they
progressively decreased in voltage as we went
through the mission.
The main batteries--every
time I checked them they always checked out at
about 9 • as far as the amps were concerned.
The
adapter batteries--I was glad we'd had the brief­
ing on them because I realized that knees on the
adapter batteries were in operation during the
launch when we got a high reading on the left
stack ammeter up around 27 or 28 amps, and we had
a reading of around,I believe,14 amps on the right
one.
I didn't alarm Jim with this information
because it was still below my cut-off point of about
30 amps or so. I felt that it was due to the knees
in the adapter batteries causing unequal loadings
of the main batteries with respect to the adapter
batteries.
Hold it .
I want to make some comments about the
electrical system and the power as we used it .
